Here we can see the location of the listener parameter file

4) modify the listener parameter file

SID_NAME, the KEY value is changed to the name of the oracle instance to be accessed, and the HOST is changed to the address used by the oracle server.

 

5) Restart listener and execute lsnrctl stop and lsnrctl start in the command line.

C: \ Documents ents and Settings \ Administrator> lsnrctl stop
